Betaxolol is primarily used in the treatment of glaucoma and ocular hypertension. It works by reducing intraocular pressure, which helps prevent damage to the optic nerve and potential vision loss. The medication is administered as eye drops, allowing for direct application to the affected area. Additionally, betaxolol is sometimes prescribed for managing high blood pressure, as it helps relax blood vessels and improve blood flow. Its selective beta-blocking properties make it suitable for patients who may not tolerate non-selective beta-blockers well. Always use as directed by a healthcare professional to ensure safety and effectiveness.
